摘　　要：目的开发合适的有机胺脱碳溶液。方法分别以PZ、1MPZ、HEP和AEP为吸收剂,考查了哌嗪类有机胺溶液的CO_(2)吸收/解吸性能。结果PZ溶液和AEP溶液的CO_(2)吸收性能明显优于1MPZ溶液和HEP溶液,但二者的解吸率相对较低,不利于有机胺溶液的循环使用。1MPZ溶液解吸率虽大于85.00%,但其易挥发性导致CO_(2)循环吸收容量大幅降低,从而使其工业应用受限。而HEP溶液的解吸率约90.00%,且经4次循环吸收/解吸实验后,其CO_(2)吸收容量和解吸率变化幅度低于1%。结论HEP溶液性能稳定,更适用于工业CO_(2)捕集过程,具有良好的应用前景。Objective The aim is to develop a suitable organic amine solution for the removal of CO_(2).Methods The CO_(2) absorption/desorption performance of piperazine-based organic amine solutions were investigated using PZ,1MPZ,HEP and AEP as absorbers.Results The CO_(2) absorption performance of the PZ solution and AEP solution was superior than that of the 1MPZ solution and HEP solution obviously,but the desorption effeciency of the two solutions was relatively low,which was not beneficial to the circulation of organic amine solutions.Although the desorption effeciency of 1MPZ solution was more than 85.00%,its volatility led to a considerable reduction in the CO_(2) circular absorption capacity,which limited industrial application.While the desorption effeciency of the HEP solution was about 90.00%,and the variation range of both CO_(2) absorption capacity and desorption effeciency was lower than 1%after 4 cycles of the absorption/desorption experiments.Conclusions The HEP solution has excellent stability,so it is more suitable for the industrial CO_(2) capture process,and has a great application prospect.
